25 Claims.

My invention relates to machines for making catamenial bandages and the like wherein a pad of soft filling material is enclosed in a wrapper of gauze or other suitable material.

The principal objects of my invention are to make and cover pads of this character rapidly and with very little labor or expense; to automatically cut and wrap the pad; to apply the wrapper so as to leave loose ends projecting beyond the ends of the pad; to provide means for satisfactorily cutting a comparatively thick layer of soft absorbent material; and in general, to provide a simple, dependable machine which operates practically without attention except to renew the stock from which the pads are made.

view partly in section Referring to the drawings, the reference numerals i and 2 indicate respectively the two end standards of the machine which have the plate 3 extending between and secured to the upper ends thereof. Pulleys or drums 4 and 5 are journaled respectively at the upper ends of the ted March 3, 1931, Serial 1924. Application for 38, Serial No. 192,585

standards length of I and 2 and carry the belt 6. the upper which runs over the plate 3. The plate 3 is provided with an opening 1 therethrough adjacent one end to receiv the upper portion of the pulley 4 so that the upper extremity of the pulley is substantially flush with the upper surface of the plate, and the other end of the plate 3 is notched as indicated at 8 to likewise accommodate the pulley 5. The belt 6, at the delivery end of the machine, passes over an idler 9, around an idler i0 and is looped around another idler ll, all of which are journaled in the standard 2, and the idler H has a belt pulley 12 secured to one end thereof and connected by the crossed belt 13 to a smaller pulley M on a stripper roll l5 which is journaled at the upper end of the standard 2. The folding of the belt around the idler H affords a substantial frictional engagement to insure a positive drive of the roll l5 which is driven in the sam direction but at a faster surface speed than the belt 5 and serves to divert the strip of material, carried along by the belt, from the latter to a cutting device which will be presently explained.

For regulating the tension of the belt 6, the shaft l6 which carries the roll 4 is journaled in bearing blocks I! which are mounted on screws (8 at the upper ends of the standard I, so that by turning the screws ill the bearing blocks I! and roll 4 carried thereby are adjustable to and from the other roll 5.

The belt 6 serves to propel a strip of pad covering material such as a gauze, along the upper surface of the plate 3 from the roll H! which is carried at the outer ends of the brackets 20 which project forwardly from the standard 1. For the purpose of permitting the roll I9 to turn freely, a pair of anti-friction rollers 21 are journaled at the outer end of each bracket 20 and support the spindle or shaft 22 of the spool 23 upon which the roll of gauze or other covering material is wound.

The strip of covering material, which is indicated at 24, is Wider than the belt 6 as shown in Fig. 3, and is led up over the rounded end edge 25 of the plate 3 under a roll 26 which is directly above the roll 4 and serves to hold the gauze against the belt 6 as it runs over the top of the roll 4, and from this roll the strip of gauze is led past the mechanism which deposits a pad of filling material thereon, then through folding devices which fold the side portions of the gauze strip over the pads thereon, and is then taken oif the belt by the stripper roll l5 and fed through a cutter which severs the gauze at points midway between successive pads.

The roll 26 is journaled in the outer ends of a pair of arms 21 which are pivoted respectively to the opposite sides of th plate 3 near the end so that the roll acts by gravity to exert the desired pressure on the gauze. For adjusting and holding the roll l3 so as to feed the strip of gauze in proper alignment with the pad feeding and strip folding mechanisms, each of the brackets is provided with a laterally and upwardly extending arm 23 near the outer end (see Fig. 3) through which an adjusting screw 23 is threaded so as to engage against the end of the shaft 22, a lock nut 33 being provided on each adjusting screw to hold the latter in the adjusted position.

A shoe 3! is arranged to bear against the periphery of the roll l3 to impose a slight tension on the strip 24, and is carried at the outer end of an arm 32 which is fixed on a shaft 33 carried by bearings 34 at the inner ends of the brackets 23. These bearings are formed with threaded stems 35 which are inserted through apertures in the horizontal web 36 of the respective brackets, and may be adjusted to various elevations by the lock nuts 33 which are threaded thereon at opposite sides of the web 35. The shaft 33 has arms 31 at the opposite ends thereof and extending at opposite sides of said shaft, and upon these arms are mounted adjustable weights 38 which may be secured in various positions of adjustment by the set screws 39. With this construction the weights may be adjusted to afiord the desired pressure of the shoe 31 against the roll i9 and the two weights afiord sufficient inertia to prevent the shoe 3| being thrown away from the surface of the roll H! by irregularity in the surface of the latter.

Referring now to the mechanism for forming the pads and depositing same on the strip 24 of gauze or other covering material, a feed table 43 is mounted on a pair of standards 4| and 42 at right angles to and somewhat above the plate 3 and has the inner end or an extension thereof projecting over the plate '3, as shown in Figs. 2 and 4, and the table supports a roll 43 of soft filling material which is confined on the table 43 between guides 44 along the side edges of the table 43. The extreme inner end of the table 43 is carried by a bracket 45 which has a depending plate portion 43 secured to the adjoining edge of the plate 3 as shown in Fig. 4, said bracket being provided with side extensions 41 with depending bearings in which a roll 43 is journaled, and the outer ends of these extensions 41 have a plate 49 secured thereto with the face thereof lying in a vertical plane substantially coinciding with the near edge of the belt 3. At the outer end of the table 43 is a roll 53 which is journaled in adjustable bearings 51 carried by screws 52, mounted on the standards 4| for adjusting the roll 53 in the same manner as the roll 4 hereinbefore described. A belt 53 passes around the rolls and 48 so that the upper length runs over the upper surface of the table 43 between the guides 44, while the lower length of the belt passes around a pair of idler rolls 54 on the standard 42, and is looped around a drum 55 which is also journaled in the standards 42.

Mounted under the plate 3 is a frame 255 carrying the driving mechanism for the machine. This frame has the main driving shaft 53, journaled therein, upon which is fixed a sprocket 51 which is connected by the link belt 53 to any suitable source of power. A number of shafts 53, 30 and BI are also journaled in the frame 255 in parallel relations to the main shaft 53, and the shafts 56, 59, and 63 have the sprockets 3!, 32 and 33 respectively fixed thereon and engaged by the chain 263 as indicated in Fig. 1, whereby the shafts 53 and are driven from the main shaft, and this chain extends upwardly around a sprocket 64 which is fixed on the shaft l3 for driving the roll 4 and belt 6. A bell crank 55 is pivoted at the elbow, as indicated at 63, on a cross brace 61 of the frame 255, and has the outer end of the arm 63 thereof connected by the link 39 to the outer end of the arm 10 which is pivoted at its inner end on a shaft 1|, which carries the drum 55. A pawl 12 is pivoted on the arm 13 and held by the spring 13 in engagement with a ratchet wheel 14 which is connected to rotate with the drum 55 so that the oscillation of the arm 10 serves to advance the drum 55 with a step by step movement. For rocking the bell crank 35, a cam disk 15 is secured on the shaft 33 and provided with a cam face 13 which cooperates with a roller 11 on the lower end of the arm 13 of the bell crank 35, said roller being held against the cam face by a spring 13 which has one end connected to the arm 33 and the other end connected to the underside of the plate 3. The cam mechanism, which I have just described, serves to intermittently operate the belt 53 to feed the strip 33 of filling material from the roll 43 to a cutter which severs the proper amount therefrom to form the filling pad. For the purpose of adjustment to permit proper engagement of the pawl 12 with the teeth of the ratchet wheel 14, the link 63 is preferably in the form of a turnbuckle, with eye members threaded on the ends so that the length of the link may be varied as required, and the eye members on the ends of the link 39 are pivoted on pins which are adjustably locked in slots 31 and B2 in the outer ends of the arms 63 and 13 respectively so that the throw of the arm 13 may be regulated to vary the extent to which the strip 30 is advanced upon each operation of the arm 33.

The roller 43 of filling material is not mounted on a fixed axis but is merely confined between abutments 33 and 34, the former of which is secured to the outer end of the table 40 and the latter of which is secured to the guides 44 and bridges the strip 83 of filling material and the belt 53 on the table 43.

For holding the strip 33 of filling material against the belt 50 adjacent the delivery end of the latter so as to insure a positive feed of the said strip, a pair of rolls 35 and 33 is mounted in spaced relation on brackets 81 which are carried by the guides 44, and have a belt 83 passed therearound so that the lower length of the belt engages the upper surface of the strip 30 and holds the latter close against the belt 53. A pair of arms 39 which is pivoted on opposite ends respectively of the shaft 33, which carries the roll 35, have the roll 3| journaled in the outer ends thereof and resting on the upper length of the belt 33 to serve as a belt tightener.

For operating the belt 33, there is a gear 92 fixed on the shaft 33, to which the idler roll 54 is attached, and this gear meshes with a gear 233 on a shaft 94 which is journaled in hangers 35, depending from the brackets 31, and this gear 233 meshes with a gear 234 which is fixed on the shaft 33 to which the roll 35 is fixed. A similar gear 93 is secured to the shaft 91, to which the roll 33 is attached, and the gears 234 and 90 mesh with an intermediate gear 90 which is mounted on a shaft 99 journaled in intermedi-- ate bearings of the bracket 81.

Immediately beyond the location of the belt 88 is a cover plate I which is mounted on the guides 44 and extends over the strip 00 of fill-- lng material, for holding the latter down against the belt 59, said plate being provided with rounded edges as shown in Fig. 4 so that the filling material readily slides thereunder.

Mounted on the under side of the plate 3 are spaced brackets IOI, each of which has a pair of depending bearings I02 in which a shaft I03 is mounted for axial sliding movement. A bracket I04 is secured on the outer end of each rod and projects upwardly and inwardly over the plate 8, and these brackets have a plate I05 secured to the inner ends thereof so that the upper surface of the plate is in the plane of the upper surface of the upper length of the belt 53, and this plate serves as a temporary support for the end of the strip 80 during the operation of severing the end portion from the strip. A pair of brackets I05 is secured to the outer edge of the plate 3 and extends upwardly and inwardly thereover with the brackets I04 interposed therebetween, and these brackets I06 have a block I01 secured to their inner ends Just above the plate I05 for stripping the severed pad I08 from the plate I05 when the latter is withdrawn from underneath the pad I08. A spring I09 surrounds each shaft I03 and is compressed between the outer bearing I02 and an adjustable collar IIO on the shaft I03 to normally hold the brackets I04 and plate I05 at the inward limit of movement thereof, as indicated in Fig. 4, and the inner ends of these shafts beyond the inner bearings I02 are connected to a cross head II I. A pivot lug H2 is formed in the cross head III midway between the shafts I03 and is connected by the link H9 to the upper end of a rocker arm II4 which is pivoted intermediate of its ends to a cross member II5 by means of a pivot pin H0. The lower end of this rocker arm II4 has a friction roll I I1 thereon which is held by the springs I09 against the side of the cam disk II8 which is fixed on the shaft 55, and has the raised cam edge II9 operating at the proper time to withdraw the plate I05 from under the severed pad I00.

A pair of guide posts I20 is mounted on the base I2I adjacent the frame 255 and extends upwardly at opposite sides respectively of the table 40, and have the upper ends connected together by the brace I22. These posts serve as a guide for a vertically reciprocable cutter which is carried by a cross head I23 which has bearings at each end slidingly engaging the posts I20. A motor I24 is mounted on this cross head I23 and may be connected by means of flexible conductors I25 or otherwise to a source of current so as to operate continuously. A rotary cutter I26 is secured to the armature shaft of the motor I24 so that the inner face thereof barely clears the outer face of the plate 49, when the cutter is depressed. and said cutter comprises a thin disk with a knife edge which has been found particularly well adapted to make a clean cut through the soft filling material with which this machine is adapted to be used. A pair of spaced bearings I21 is formed on the cross head I23 at opposite sides respectively of the motor I24 to slidingly receive the shafts I28, to the lower ends of which is secured a shoe I29. Each shaft I28 has a spring I30 thereon interposed between the bearing I21 and the shoe I29 for resiliently holding the shoe in the lowermost position which is determined by collars I3I which are adjustably secured on the upper ends of the shafts I28 above the bearings I21. This shoe I29 is of a suitable width to extend substantially from the outer edge of the guide I00 to the block I01, as shown in Fig. 4, and serves when the cross head I23 is depressed, to resiliently clamp the end portion of the strip of filling material on the plate I05, the outer end of the belt 53 and adjacent portions of the framework over which the strip 80 passes, and this shoe has a slot I32 through which the cutter I26 is projected after the movement of the shoe I29 is interrupted by coming in contact with the upper surface of the strip 80.

The cross head I23 is connected by a pair of parallel rods M9 to a lower cross head I34 which likewise slides on the posts I20 and is located underneath the table 40. This crosshead I34 is divided intermediate of the ends to receive the upper end of the link I35 therebetween which is pivoted on the pin I35, which latter has the ends engaged in the opposite sides of the divided portion of the cross head. The lower end of this link I is pivoted to the crank pin I31 of the crank I 38 which is secured to the outer end of the shaft 6|, which shaft is driven by means of the gear I39 which is fixed thereon and meshes with the gear I40 which is fixed on the shaft 60. By reason of this connection, the continuously driven cutter I26 and shoe I29 is reciprocated to and from the supported end of the strip 80, the parts being so timed that the strip 80 is intermittently advanced, being fed forward while the plate I05 is in the position shown in Fig. 4, whereupon the advance movement of the strip 80 is interrupted while the cutter is depressed to cut off a portion I08 from the end of the strip, after which the cutter and shoe are elevated and the plate I05 withdrawn to permit the severed pad I08 to drop down onto the continuously moving strip 24 of gauze or other wrapping material. Immediately after the pad I08 is discharged as aforesaid, the plate I05 is returned to the position shown in Fig. 4 and the strip 80 advanced another step, whereupon the cutter again descends.

To facilitate the vertical reciprocation of the cutting mechanism, a counterweight I65 is provided therefor, which is carried by a chain I66 which is passed over an idler I61 and connected to a hook I58 on the lower cross head I34. The idler I51 is mounted on brackets I09 which are secured to the standard 42.

In order to insure proper deposit of the pad I08 onto the moving strip 24 of gauze or other covering material, it is desirable that the forward end of the pad should come in contact with the moving strip 24 before the rear end thereof comes in contact therewith, and to accomplish this result a plurality of inclined guides I4I are secured to a bracket I42 which is mounted at the rear end of the strip I01 so as to incline downwardly and forwardly under the rear end of the pad I08. These guides or fingers retard the dropping d-own of the rear end of the pad until the forward end thereof engages the moving strip 24 and is drawn forwardly thereby.

After the pads I08 are deposited on the strip 24, they are carried by said strip and the belt 6 between folding members I43 which are mounted on the plate 3 at opposite sides of the belt 5, and serve to fold up the side portions of the strip 24 in the manner shown in Fig. 11, against the side edges of the pads I08. Beyond the folders I48 are successively arranged iolder plates I44 and I45 positioned respectively at opposite sides of and extending over the belt 5 at a suitable elevation to first fold one side of the strip 24 over the pads I08 and then fold the other side thereover as shown in Figs. 9 and 11 to 14 inclusive, with the opposite sides of the strip 24 overlapped over the pads. A shoe I48 may, if desired, be pivoted on a bridge I41 over the belt 8 near the delivery ends of the folders I43 to prevent overthrow of the side portions of the strip 24 before the side portions reach the folders I44 and I45.

Mounted on the standards 2 at the delivery end of the machine is an inclined chute I48 which has the upper end positioned adjacent the stripping roll I5 so that the latter delivers the folded strip 24 and enclosed pads onto this chute between the guides I48 which are secured to the side edges of the chute. This chute is pivoted near the upper end on a hanger I50 which has the ends secured to the standards 2, and the lower end of this chute is resiliently supported by one or more springs I5I which are seated in a block I52 carried by a bracket I53. This bracket has a ledge I54 beyond the end of the chute I48 to which a shear blade I55 is adjustably secured by the cap screws I55. This shear blade extends across the end of the chute I48, and the cutting edge is normally below the outer surface of chute I48 in the position in which the latter is normally held by the springs I5I, the parts being so arranged that the folded strip 24 and pads therein readily pass off the end of the chute I48 without interference from the shear blade I55.

A pair of brackets I51 is secured to the standards 2 and have a shaft I58 journaled thereon and the shaft is provided with a cutter head I58, to which a shear blade IE is secured by bolts II so as to swing around with the shaft I58. This shear blade I80 cooperates with the shear blade I55 to sever the folded strip 24 at predetermined intervals. Proper adjustment of the shear blades I55 and I80 is effected by adjusting screws I82 and I58.

Inasmuch as the lower end of the chute I48 is normally raised slightly above the cutting edge of the shear blade I55, it is necessary to depress the lower end of the chute at the time of the shearing operation, and to this end the cutter blade I60 is extended somewhat beyond the sides of the chute I48, and the lower ends are beveled as indicated at I64, so that as the cutter I60 nears the cutting position, it engages the beveled edges I64 of the guides and depresses the lower end of the chute I48 sufficiently against the tension of the springs I5I so that the cutting edges of the shear blades may cooperate.

The cutter IE0 is rotated at a rate of speed corresponding to the rate of movement of the folded strip 24 so that as the cutter comes to the cutting position, it neither retards nor pulls on the strip, and moreover, the cutter I80 is disengaged from the lower end of the chute I48 as the shearing operation takes place, and thereby permits the immediate elevation of the lower end of the chute I48 so that the leading end of the folded strip 24 is readily advanced over beyond the cutter I55.

For conveying the severed pads away from the lower end of the chute I48, I have provided a conveyer belt I which passes around a drum I1I on the standards 2 and over idiers I12 on a guides I48 at their standard I18 so that the upper length of this belt passes under the lower end of the chute I48 in the direction indicated in Fig. 8. This conveyer and cutter I58 are both driven by a chain I14 which passes around and is driven by a sprocket I15 on the shaft BI, said chain being guided around the sprocket I18 on the cutter shaft I58 and the sprocket I11 on the shaft I18 of the drum I1I by an idler I18 on the shaft I which carries the drum I0 and the sprocket I8I which is carried by adjustable brackets I82 on the standards 2. Adjusting screws I83 are provided in connection with the brackets I82 for regulating the tension of the driving chain I14.

In the operation of this machine, the pads I08 are deposited at regular intervals on the strip 24 of gauze so that a considerable length of gauze intervenes between successive pads so as to leave loose ends of the enclosing gauze on each pad as shown in Fig. 15. It is desirable to out the gauze midway between the successive pads so that the loose ends I84 are of uniform length, and this necessitates the synchronizing of the cutter I60 with the mechanism which advances the strip 24 and particularly with the mechanism which severs and deposits the pads I08 onto the moving strip 24. In order that these mechanisms may be properly synchronized, the upper and lower lengths of the chain I14 are passed respectively under and over idler sprockets I and I88 which are adapted to be simultaneously raised or lowered to vary the time of the cutting operation of the cutter I80 with respect to the strip feeding mechanism and the pad depositing mechanism. These sprockets I85 and I88 are journaled in a block I81 which slides between the guides I88 of the standard I88, and is adapted for vertical adjustment by a hand wheel I80 which has a stem I8I journaled in an offset bearing I82 of the standard I88 and held against axial movement by engagement of the bearing I82 between the hub of the hand wheel I80 and the collar I83 on the stem. The lower end of this stem I! is threaded and engages a threaded aperture in the block I81 so that by turning the hand wheel I80 the block I81 and sprockets I85 and I88 are raised and lowered. Idlers I84 are journaled on the standard I88 above and at opposite sides of the sprocket I85 and have the upper length of the chain I14 passed therearound, as shown in Fig. 1, and similar idler sprockets I85 are mounted on the standard I88 at opposite sides of and below the sprocket I88 to engage the lower length of the chain I14 in a similar manner. By this arrangement, it will be observed that when the hand wheel I80 is turned so as to raise the block I81 and the sprockets I85 and I88, the upper length of the chain I14 is shortened while the lower length is correspondingly taken up, and this results in a backing up of the cutter I80 so that the cutting operation is delayed, while operation of the hand wheel I80 in the reverse direction in a similar manner advances the operation of the cutter I80. Thus the point between the ends of the successive pads I08 at which the strip 24 is severed may be accurately regulated so that the loose ends I84 are of a uniform length.
